This issue has happened a couple of times and it's pretty annoying...Basically if I close my lid, go to sleep and wake up the next morning, when I open the lid up, everything lights up (screen, keyboard) right where I left it, but nothing is controllable, AKA the mouse is frozen, any key shortcut doesn't work, basically nothing happens. I left it for a couple of minutes before I restarted, and it's fine then, but I was wondering if anyone else has noticed this issue. It's only happened since I upgraded to ML, and I really hope it's not a hardware issue (my guess is that if it was, it'd be a SSD issue?). Thanks for everyone's help.
